My V6 box which i have had for around 5 months has recently started rebooting randomly. I always put the box into standby when not in use, it really only get switched on a few times a week for football. The screen will go black, my tv will say no signal found, some white noise will appear. When the box comes out of standby mode, it usually displays picture ok, but as soon as channel is change will reboot. If I remove the HDMI at back of the box and put it back in again the picture will appear back on the screen. Have different HDMI cable to see if it's the cable, but still have the same issue.
